Basic difference between ac-dc magnetic coil

Structurally and physically there is no difference between AC and DC electromagnetic coil. Both are made by wrapping the wires around dominant. Electro magnets DC is the most important metal or metals. Electro-magnetic coils AC "core" will air.

The difference is that they function and purpose. DC electro-magnetic coils can be used electromagnets, solenoids and relays. All other records of the electro-magnet coils can be used for AC applications.
